The entire benefit of her effect would be cheesing out something big, so having to play her as a sub-standard 6 drop for a chance at that makes her gimmicky in decks that aren't gimmickly built around her.

I wonder if making her a 6 mana 4/6 like Reno Jackson would be a good change. Both require a lot of building around them to work, but have potentially very powerful effects.

Even then, she seems like she'd be weaker than Jackson with less consistency and a mostly dead draw later due to the weak minion going to the deck.

And even when she plays a massive beater in exchange for a wisp, one still has to face the extra RNG of whether or not the opponent has a kill spell.

It is fun! Shame that you don't have that Y'Shaarj, because he is the best creature to combo with Goya. Also very nice card to play after board clear. Y'shaarj is not very useful legendary overall, had seen it only in some rare ramp or astral druid decks.

Made one game play video for those who are interested, got very lucky in this one.

Reno is different the effect is really strong and you don't need tonnes of support to play him with this you need like only play token spells and big legendaries which their stats matter or they are ragnaros/sylvanas but then.. why not just play sylvannas/rag instead of a 6 mana 4/3 that kills a minion (tempowise at least) and then summons a random one from your deck I think it would only be good if you could choose the minion to get.. otherwise why not just play it?
